Added hi res avatars for the dialog box.
Move addClickTouchEvent helper to utils from base.
Add stub Dialog for serverless Blockly.
Added options for icon and close button to client dialog.
Move most feedback related stuff to a new file. Parameterize feedbacks and make them instances instead of a singleton in the DOM.
Move templates to subdirectory. Remove static DOM stuff from page since it is now handled dynamically in base and feedback.
Mostly styling and asset stuff.
Swap order of dialog show and add event listener to be more readable.
Added back dynamic size of hint bubble.
